Comment 26 for bug 222163

Same issue here:

- Kubuntu 8.10 Intrepid Ibex
- AMD64 X2 4400+ Dual-Core
- ATI/AMD Radeon HD2400 PRO
- fglrx driver version 8.543 from Ubuntu repos

The difference to others here to my case is that it can't be reproduced exactly. Sometimes it just happens when I log into KDE4 and the first window from the last session is about to be displayed. Then it crashes X with a stacktrace similar to the reporter of this bug and I get a blinking cursor in text mode on the black screen but cannot type anything, no prompt, nothing.

My case is somewhat different as I can still change between TTYs so I went into TTY1 and issued a ps to see that X is a zombie running at 100% CPU on one of my cores. I can issue all commands just normally (maybe because the other core is free for use). But when I try to do something like "/etc/init.d/kdm restart" the system crashes hard when it tries to terminate the defunct X.

I didn't have that problem before using Ubuntu 8.04 Hardy Heron neither with KDE3 nor XFCE.

I'll still have to try out if the problem persists when I try to disable all effects under KDE4.
